Finger cursor using gesture recognition

Since the computer is developed we are using mouse for cursor movement. In this era of touch screen devices human machine interaction is very important factor nowadays. Many devices are developed which can be operated without touching the system. So there should be any system in computer and laptop also to operate them without touching physically. So in this paper we have described new concept named `Finger Cursor'. It means operating computer's cursor using our finger's gestures. In this paper we have described methods and algorithms we have used for this system. We have described methods for color detection, image filtering, finding centroid and bounding a box to it, mouse movements and executing mouse events.
